Xenon Web Lightning - Version 2.1.0 Multi-Award Winning. A completely unique program that speeds up website download times to pages you visit often. Once you add a site you can close the program and continue to enjoy the great increase in page load times. Nothing is saved in a cache and once a site is added you no longer need the program running, so absolutely no extra memory is needed! You can add either a single site/domain, or all of your Internet Explorer, Opera and Netscape bookmarks with a single click!
